Description

Solid door lock

The utility model relates to the accessory in a kind of building construction.

Generally have two kinds by the gate at two fans the gate, particularly wooden structures formed, the mode of locking a door, a kind of is to nail on knocker respectively on two fan doors, and bolt is made with wood materials, when locking a door, bolt is through in two knockers just to become, as shown in Figure 4; Another kind is that bolt is made with the garden steel, and a ring is arranged on the bolt, and when locking a door, bolt inserts in the knocker, and ring set is buckled at another door and added a lock, as shown in Figure 3.Though above-mentioned two kinds of door locks are simple in structure, use also more conveniently, can only be that the people in the door uses, people outdoors will lock, and just open can not, so they have significant limitation.

The purpose of this utility model is to solve above-mentioned defective, and a kind of Solid door lock is provided.

The technical solution of the utility model is achieved like this.The bolt steel is made, and at an one plane processing tooth, make it become a toothed rack, bolt can be movable in button, and is movable back and forth for making bolt, dispose a gear, the point wheel is fixed in the box by axle, and two of axle is fixed with handwheel, rotates handwheel inside and outside door, bolt is moved around, thereby reach the purpose of locking a door or opening the door, also can pin bolt outdoors, a cover mechanism is installed again in its lower section in order to make, promptly control cam with cylinder lock, again by the cam pushing pin, pin is inserted in the pin-and-hole of bolt, there is not the key door of just don't looking on the bright side of things like this, latch locking bolt in owner can use in door the time prevents that the stranger from opening the door.

The utility model modern design, rational in infrastructure, strong reliable, easy to use.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is a sectional view of the present utility model.

Fig. 2 is user mode figure of the present utility model.

Fig. 3, Fig. 4 are the schematic diagram of prior art.

As shown in Figure 1 and Figure 2, box (24) is fixed on the door (1), gear (3) is fixed on the axle (20) by key (15), the right-hand member of axle (20) passes door (1), and handwheel (25) is by key, and pad and screw are on axle (20), nut (26) is fixed on axle (20) on the box (24), the left end of axle (20) passes through key (17), pad (18), and screw (19) is fixed handwheel (16).Be enclosed within the knocker (21,22) with the bolt (4) of gear (3) engagement, knocker (23) is fixed on other Yishanmen, and pin (5) is through in the hole (28) of the tappet (6) that is fixed on the box (24), up and down can be movable.Be mounted with below the pin (5) with key (13), nut (12) is fixed on the cam (7) in the lock core shaft (8), lock body (9) is screwed on door (1), for preventing lock core shaft (8) play back and forth, limits with snap ring (11) and packing ring (14).There is the pin-and-hole (27) that can hold pin (5) appropriate location of bolt (4).When locking a door, rotate handwheel (25) or handwheel (16), mobile bolt (4), bolt (4) is inserted in the knocker (23), again key (10) is inserted lock core shaft (8) and rotate, make cam (7) jack-up pin (5), insert in the pin-and-hole (27) of bolt (4), extract key out, door just is lockable.In the time will opening the door, earlier key (10) being inserted lock core shaft (8) rotates, make the constraint of cam (7) disengaging to pin (5), pin (5) freely falls, the constraint that also breaks away from pair of latches (4), rotate the mobile bolt of handwheel (25) (4) again, make it extract knocker (23), then door just can be opened.Also can to pin bolt (4) in order making in door, to have set up an interior latch (29), and fix and go up in position, as shown in Figure 2, interior latch (29) is fixed on the knocker (22), on the corresponding position of bolt (4) at least one pin-and-hole is arranged.
